Find the area of the region between the two concentric circles, if the length of a chord of the outer circle just touching the inner circle at a particular point on it is 10 cm (Take, `pi = (22)/(7)`)

Explanation

To find the area of the region between two concentric circles, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: We have two concentric circles (one inside the other). A chord of the outer circle touches the inner circle at a single point, and the length of this chord is given as 10 cm.

2. **Identify the Geometry**: Let:
- \( O \) be the center of both circles.
